SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 432,639, dated July 22,1890.

Application filed May 15, 1890. Serial No. 351,882. (No model.)

To aZZ whom it may concern.-

Be it known that I, THEODORE NEWTON, of Hartford, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Sash-Fasteners, of which the following is a full, clear,and exact description, whereby any one skilled in the art can make anduse the same.

My invention relates to the class of devices that are secured to awindow-sash for the purpose of fastening the same; and the objcct of myinvention is to provide a simple but efficient device, by means of whichthe two sashes may be fastened together, so that a space may be lefteither at the top or bottom of the window for ventilation an d yet holdthe two parts of the sash firmly together in such manner that theycannot be opened to any greater or less extent without releasing thefastening.

My invention consists in details of the several parts making up thefastening device as a whole,'and in their combination, as moreparticularlyhereinafter described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a view in front elevation ofawind'ow, showing two sashes fastened open by my improved device. Fig. 2is a detail front View, on an enlarged scale,of the siderails of twosashes. Fig. 3 is a detail top View, on an enlarged scale, incross-section through one sash and through the bolt-case of'thefastener.

In the accompanying drawings, the letter a denotes a Window-frame; l),the upper sash; c, the lower sash having the meeting-rails I) 0,respectively.

The fastener D consists of a bolt-case (Z, within which a sliding androtary bolt e is supported. This bolt-case is adapted to be fastened onthe top of the ineetingrail 0', so that the locking end e of the bolt 6projects into a recess formed in the side rail b of the upper sash. In asocket in the upper sash a catch-plate fipreferably formed of metal andhaving a lengthwise slot f, is secured. On one or both sides of theslot, preferably on both, and within the socket are locking-recessesinto which the T-shaped fastening end of the bolt e is adapted to fit.The slot is of such width with relation to this fastening end that thelatter may be readily pushed through the slot when it is in an uprightposition; but when the bolt is rotated .a quarter-turn the locking endof the bolt will, when slid forward, engage the recessesin thecatchplate. A spring g is located within the boltcase (Z with one endthrust against a shoulder on such case and the other thrusting against apin or shoulder on the bolt in such manner as to cause the bolt to benormally held against forward sliding movementin the case, the tensionof the spring operating to draw the two sashes together when the lookingend of the bolt is engaged with the catchplate on the opposite sash. Thebolteis provided with a handle 6 located conveniently of access outsidethe case, and by means of it the bolt may be engaged with or disengagedfrom the locking-recesses in the catchplate. By grasping the handle 6and pushing toward the sash the bolt is slid forward until its endenters the recess in the opposite sash, passing through the slot f, andthe bolt is guided in this movement by a pin 2, that projects from thebolt and travels in a lengthwise slot in the case.' A branch slot fromthe first allows the bolt to be turned a quarter-turn, so as to throwthe locking end transversely across the slot and adapt the projectingends to engage the sockets in the back part of the catch-plate as soonas .the pressure upon the bolt is removed, so as to allow the spring tothrust the bolt backward, as it will do as soon as the pressure upon thebolt is removed.

I do not limit myself to the particular construction of the bolt-caseand engaging parts of the bolt end and socket-plate; 1101' to thespecific location of the handle, as these parts may be evidentlymodified without avoiding the main feature of my invention.

I claim as my invention- 1. In combination with the sliding sash, thelock-case adapted'to be secured to one of the sashes, a sliding boltborne in the lock-case and having a limited rotary movement, a springoperatingto hold the bolt in its retracted position, the handleappurtenant to the bolt, and the catch-plate bearing the inward-facinglocking-sockets, all substantially the bolt, and the guide-socket in thebolt as described.

case, all substantially as described. 2. In combination with a slottedcatchv plate having inward-facing locking-sockets 5 arranged adjacent tothe slot, a bolt-case supporting a spring-seated sliding bolt with a T-shaped fastening end, the guide-pin borne on THEODORE NEWTON. Witnesses:
